gflags: correct S and update library install directory
gflags: correct S and update library install directory

The current setting of S is not right for multilib. Remove the setting
and use the default value.

And library install directory is not right for multilib either. It fails
with [installed-vs-shipped] QA error:

| ERROR: gflags-2.2.0-r0 do_package: QA Issue: gflags: Files/directories
| were installed but not shipped in any package:
|   /usr/lib/libgflags.so
|   /usr/lib/libgflags_nothreads.so.2.2

Set cmake variable LIB_INSTALL_DIR with ${baselib} to fix the issue.
